Like most islands, the Galapagos
counts sea gulls among its population of sea birds. Surprisingly,
however, the two species of gull found in the Galapagos are
both unique species, found nowhere else. The beautiful Swallow-tailed
sea gull, with its striking red eye rings, is the only sea gull
in the world that fishes at night. The rare lava gull gets its
name from its dark gray plumage that camouflages it on the dark
lava rocks. The entire breeding population of lava gulls consists
of only about 800 breeding pairs.
